Pegasus Astro DewMaster

DewMaster was made for the visual astronomer. Connect up to five dew heaters and control them individually using PWM duty cycle.

Full digital operation and a high resolution red film display makes the control of the device quick and simple. Measure consumed Amperes and Input voltage by a glimpse of an eye.

Optionally, an external temperature and humidity sensor will let you know the levels of the relative humidity, temperature and dew point.

Automatic dew heaters control will let you relax as you know that in case of high levels of humidity your optics will be moisture free!


  • Five Channel RCA Outputs for Dew Heaters
  • Pulse Width Modulation (PWM) Duty Cycle Control with Automatic Dew Control
  • Full Digital Operation
  • Easy to Use
  • Red Film LED Display
  • Reverse Polarity Protected
  • Two pass-through DC Outputs with Amp-Meter Showing Current Consumption

Red Film LED Display

A 128 x 64-pixel Organic LED (red film) screen is used for the device.

This display works lag-free, at very low temperatures.

The red film on top of the display ensures that your night vision is going to be unaffected.
On the left, images show the on-screen display menus of the DewMaster.

External Environment Sensor ( * Included)

An external one (1) meter high-resolution temperature & relative humidity calibrated sensor will let you know the environmental conditions of your site. The sensor can be auto combined with the dew heater outlets to automatically adjust the power levels.

Leave it to the DewMaster to decide if it is time to turn on your heating elements! You can also monitor the readings of temperature, humidity, and dew point on the display screen.

* Environmental sensor is now included in the package at no extra cost – Please note that the new sensor is in blue color and is compatible with newer firmware only.

Two pass-through DC outputs and an Ampmeter

Two 12V DC outputs let you connect additional equipment with fewer and shorter cables

The device includes an Amp-meter which displays the total current consumption of the device, DC outputs, and dew heater channels.
